Upgrade Your TMIC with the GrimmSpeed Splitter

Is your OEM splitter holding back your performance? If you're a proud owner of a 2006-2007 Subaru WRX or STI, you know how crucial it is to keep your top mount intercooler (TMIC) fed with cool, ambient air. The factory splitter can choke airflow, leaving your upgraded TMIC working harder than it should. Whether you've installed an STI scoop or are simply looking to maximize your current setup, the GrimmSpeed TMIC Splitter lineup offers the perfect solution.

Why Upgrade?

With even mild modifications, your Subaru can generate significant heat. As your turbo compresses the intake air, temperatures can soar to over 400°F before reaching your TMIC. If you're still using the stock WRX splitter, you’re not harnessing the full potential of your intercooler. The GrimmSpeed splitters enhance airflow by a whopping 70%, ensuring your TMIC gets the cool air it needs to perform at its best. Larger TMICs can increase internal core volume by up to 200%, and you’ll want every bit of that additional airflow to keep your intake temps down.

Key Features

• 70% increase in flow capacity to your TMIC, dramatically improving heat dissipation.
• Maximizes TMIC efficiency, resulting in lower outlet temperatures and allowing for more aggressive tuning.
• Designed for even flow distribution to ensure the entire core effectively cools the hot charge air.
• CAD-designed for optimal fitment and functionality.
• CNC laser cut from 5052 aluminum for superior durability against heat and vibration.
• Finished with a durable DuPont black powdercoat for an OEM-like appearance and protection.
• Includes a custom EPDM rubber gasket for excellent sealing and longevity.
• Equipped with three intercooler sprayer ports to utilize your STI TMIC sprayer or to add one if desired.
